+heroText: The task library that just works
+tagline: A sensible set of task to build, test, and lint your frontend projects
+actionText: Get Started →
+actionLink: /tasks/
+features:
+  - title: Flexible
+    details: 'Unlike create-react-app, just gives sensible defaults but does not hide config files'
+  - title: Task orchestration
+    details: Like gulp, just provides parallel() and series() to fine tune task runs
+  - title: No waiting for latest devDependencies
+    details: just-scripts knows how to run tools, but it does not prescribe versions of the dependencies - you upgrade at your own timing!
+  - title: TypeScript suport
+    details: just-scripts configurations are TypeScript-enabled, so you don't have to have a separate build step to use your build tools
+  - title: Lightweight task orchestration
+    details: just-task is a lightweight task orchestrator that has no streaming file system abstraction
+  - title: Battle tested
+    details: just is built upon just the right abstraction from the gulp ecosystem, which is used by many repos
